#1 Dolph Ziggler

Dolph Ziggler is possibly the one person who is assured to get a main-event place on the roster of AEW if he were to go to the promotion. When it comes to WWE, it is now a foregone conclusion that Ziggler might not be able to get past an upper mid-card position on the card.
He has become the gatekeeper in WWE and it is extremely unlikely that he will get another major main-event run in the company. Ziggler has been around for a long time and his gimmick has become rather stale with the WWE Universe.
However, in AEW, he would be able to start on a completely fresh page. Ziggler is one of the best Superstars in the world when it comes to in-ring technique, a side of himself that he has shown in WWE only on occasion.
Given the right push, in AEW, be it as a heel or a face, Dolph Ziggler would be able to get over and play the role that AEW needs him to play. He would be the perfect signing for AEW.
